[Year 12 SofDev] Assessor's report

[Poultney, Gordon A]

re: control arrays  They work ok in VB.NET  if imported from VB6.

The indexing convention used is unusual but you can work with an array of controls as per VB6.

See attached template for Hangman - imported from VB6. Excuse the abstruse wordlist created a student 10 years ago!

Imaginatively named textboxes are renamed as:_Txt1_1, _Txt1_2,  _Txt1_3 etc
Yet in code are accessed thus:

For i = 1 To 10
            Txt1(i).Text = ""
            Txt1(i).Visible = False
        Next



I assume there are better ways than this, but I just whip up the control array in VB6 then import to .net.

cheers
           Gordon

Hi folk.  Sorry for posting about the ITA assessor's report to this list. I hope I didn't confuse you too much.

I've had SD on the brain recently* and forgot the complaint was about ITA.

*I'm finally nearly semi-competent in VB2010 and starting to forget my old VB6 habits, but I certainly miss control arrays.
Why MS ditched them I'll never know.  It use to be SO easy to loop through an array of controls and do things with them, e.g.

For i =1 to 99
  checkbox(i).checked = false
next

Sadly, you can't do that easily any more.
